LAMP-BURNER.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed January 13, 1913. Serial No. 741,866.

To all whom it may concern:

Be itknown that I, FLORIAN DANUSER, a citizen of the United States, residing at Tacoma, in the county of Pierce andState of Washington, have invented certaln new and useful Improvements in Lamp-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in burners for kerosene lamps.

The main object of the invention is to provide simple means whereby the heat at the end of a burning wick will be greatly intensified and the light produced will be white, intense and clear without increasing the consumption of oil or wick.

Another object is to provide simple means for controlling the flame and thereby avoiding breakage of the chimney.

Still another object is to construct a burner to permit the wick to be raised to any height without smoking, even when the wick is raised to a level with the dome slot.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 represents a side elevation, partly in section, of a lamp burner constructed in accordance with this invention; Fig. 2 is a similar view taken on a plane atright angles to that shown in Fig. 1; Fig. 3 is a top plan view thereof; Fig. 4 is a detail transverse vertical section taken through the dome of the burner across the flame opening therein.

In the embodiment illustrated a burner of ordinary construction is shown having the usual gallery A and wick tube B with a hinged dome O.

This invention resides in an attachment which is applied to the dome and comprises two copper wires 1 and 2 arranged on opposite sides of the flame slot 3 in a plane above the upper end of the wick tube. These copper wires 1 and 2 constitute generators which immediately become red hot on the lighting of the wick thereby producing an extreme heat at this point which serves to produce a strong draft of air thr ugh the dome which unites with the oil gas above the upper end of the wick tube and forms a thin white flame, and the heat so generated is directed upwardly through the open end of the chimney without overheating the side walls thereof. This is accomplished by means of air apertures 4 arranged in the dome in alinement with the flame opening and in a plane below the ends thereof as is shown clearly in Fig. 2. The flame opening or slot 3 here shown tapers toward its opposite ends being wider at the center thus forming a substantially oval slot which is especially adapted for use with the copper wire generators which produce a heavy central draft or suction and by so forming the slot a straight flame is produced without necessitating the corners of the wick being trimmed as is usual in lamps of this character. The free upper end of the wick tube B is arranged in the same plane with the side draft openings 4 and this location of the upper end of the WlGk tube prevents all smoking of the wick even when said wick is raised to a level with the dome slot.

The copper wires 1 and 2 which form the generators may be secured in the dome in any suitable manner and are here shown extended through the side walls thereof adjacent the opposite ends of the flame slot and are bent into retaining eyes 5 to prevent accident-al displacement of said wires. The copper wires employed will not collect soot and therefore, the burner is always clean and ready for operation. The arrangement of these copper generator wires 1 and 2 not only produces a clean gas by drawing up the air into contact with the kerosene supplied by the wick but also produce a strong, pure, white light and so directs the flame as to prevent it from impinging on the side walls of the chimney. A test of the burner proves that the flame is retained at least from three-fourths to one inch away from the glass and the air draft so drawn up by the1 wires also serves to keep the burner coo In the use of these improvements, the

burner having been applied to a lamp filled light so produced is extraordinarily bright While it consumes a minimum quantity of oil and is smokeless and odorless.

I claim as my invention 1. A lamp burner having a dome provided' with a flame slot, independent parallel copper Wires extending transversely. of said dome in a plane above the Wick tube and spaced laterally from opposite sides thereof, said Wires being arranged parallel with said flame slot 0n opposite sides ,thereof and substantially in the same-horizontal plane as the ends of said slot.

2. A lamp burner having a dome provided with a flame slot, independent parallel copper Wires extending transversely of said dome in a plane above the WlCktube and spaced laterally from opposite sides thereof, said Wires being arranged parallel plane as the ends of said slot, the ends of said Wires extending through the Walls of said dome and bent to form retaining elemerits.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
